Q31.
Which one of the following statements regarding DSI is wrong?

a.

It is a digital form of TASI

b.

Though it is more efficient than TASI, it is much slower

c.

A speaker has to wait (it at all) for only a few milliseconds for reallocation of channel

d.

It has increased the capacity of satellite channels by a factor of 2.2 or more with out degrading speech quality

Discuss
Answer: (b).Though it is more efficient than TASI, it is much slower
Q32.
Which one of the following statements regarding compandor is FALSE?

a.

It compresses the higher-amplitude parts of a signal before modulation and expands them back to normal again after demodulation.

b.

It gives preferential treatment to the weaker parts of the signal

c.

For weaker signals it gives a poor ratio of signal strength to quantizing error

d.

Weaker signals, traverse more quantum steps than they would do otherwise and so quantizing error is reduced.

Discuss
Answer: (c).For weaker signals it gives a poor ratio of signal strength to quantizing error
